Just months before her arrest, accused Australian drug smuggler Cassandra Sainsbury made a number of posts to her social media account indicating a “life-changing” event and her excitement about travelling.

Seven News has confirmed the Drug Enforcement Agency (DEA) in the US tipped off police in Colombia that Ms Sainsbury was allegedly carrying almost 6kg of cocaine in her suitcase when she was arrested on April 11.

On January 24, she wrote another post, which has also since been deleted, which read: “Moving interstate driving me cray cray! #save me! Not long before the big move now, super excited and can’t wait to leave so much baggage behind.”

Both Instagram posts contain hashtags indicating travel or relocation to Sydney, possibly around March 1 (when the 50 day count down ended).

Her social media trail places her in China later that month and in the US in early April.

She appears to have caught a connecting flight to Bogota from LA because authorities record her as having arrived in Colombia on the same day — April 3.

On April 8, she posted a photograph from Bogota along with the comment: “Can’t complain about an all expenses paid work trip, in which (sic) is mainly holiday very little work. It’s the simple things that are the true beauty in the world. Mother Nature has been putting on quite the show for me over here.”
